This page is an independent, self-produced work, unaffiliated with Yubu Island or its facility. That Yubu belongs to Taketomi Town, its smallness (2.15 km around; 1.5 m above the sea), the shallow sea between it and Iriomote (about 1 m even at high tide), the introduction of the island as “a subtropical botanical garden in its entirety”, and the about 30 kinds of hibiscus with more than 100 kinds of plants in all rest on the introductions of Taketomi Town and the Taketomi Town Tourism Association. That the ways across are by water-buffalo cart or on foot, the cart's one-way time of about 10–15 minutes, how the island came to be (settlement from Taketomi and Kuroshima; Typhoon Elsie in 1969; the late Seiji Iriomote and his wife with one water buffalo; the buffalo's arrival on Ishigaki around 1932 with settlers from Taiwan), and the bougainvillea garden, butterfly house and Manta Beach rest on the Yubu Island official site and the tourism association. The introduction of crossing to the sound of the sanshin rests on the tourism association's travel guide. The local bus from Ohara Port (about 22–25 minutes) rests on the tourism association and the official site; the high-speed boat between Ishigaki and Ohara (about 35–50 minutes) on several operator-side guides, which differ. All of this was confirmed by 2026-11-01, in part at summary level via search-result titles and summaries. Scenery descriptions and passages on how to spend the time are editorial. Fares, opening hours, buffalo-cart, boat and bus times, and booking methods are deliberately not carried on this page — always confirm them officially at the time of travel.
